EMS Physician Scene Response Program
Emergency physicians, on scene with Kennebec Valley EMS
MD3 of Maine is a nonprofit EMS physician response program. When local fire and EMS crews are caring for a critically ill or injured patient, they can request an emergency physician to join them on scene, bringing hospital-level skills, medications, and decision-making to the patient’s side.

Our mission
Bringing emergency medicine to the patient’s side
MD3 physicians respond alongside local EMS and fire crews to the region’s most complex and critical calls. They perform advanced procedures in the field, guide difficult medical decisions on scene, and partner with receiving hospital teams so care is seamless from the scene to the emergency department.
Every response is also a chance to teach and to learn. MD3 invests in the EMTs and paramedics who serve the Kennebec Valley every day, and in the emergency care system that supports them.
How a response works
-
1
A 9-1-1 call comes in
Dispatch sends local fire and EMS crews, just as it always does.
-
2
The crew requests MD3
When a patient needs physician-level care, the responding agency requests MD3 through its dispatch center.
-
3
A physician joins the team
An MD3 physician responds to the scene, works side by side with the crew, and coordinates with the receiving hospital.
MD3 is requested by public safety agencies only. If you are experiencing a medical emergency, call 9-1-1.

Program goals
More than a response
MD3 is built around three goals that strengthen emergency care across the Kennebec Valley.
Teaching and learning
We offer formal continuing education courses along with real-time feedback on scene and after calls. The learning goes both ways: our physicians gain from the expertise and real-world experience of our fire and EMS partners, building mutual respect and system-wide improvement.
Enhanced patient care
MD3 physicians bring experience, specialized tools, and medications to complicated situations, from high-risk refusals and combative patients to mass casualty events, HazMat incidents, and critical care transports.
EMS system support
We are committed to strengthening how the regional emergency care system is designed and how it performs, providing direct feedback to our partner agencies, EMS leadership, and receiving hospitals.
Field-ready standards
Trained for the realities of the field
All MD3 physicians work in emergency departments at hospitals across Maine, and each has received specialty training to function as an EMS physician in the field. Many are board certified in EMS or bring extensive experience as prehospital providers, from EMT to paramedic.

When does MD3 operate?
MD3’s operational goal is to provide coverage Monday through Friday, from 9:00 AM to 5:00 PM. Actual availability during these hours can vary based on staffing.
We continually analyze community needs to align our coverage with peak demand, and our long-term goal is to expand into evenings and weekends as the organization grows. That expansion is only possible through the generosity of our community. Make a donation to help us get there.
Does MD3 charge for its services?
No. There is no charge for MD3’s services. We never send a bill to patients, and we never bill the public safety agencies that request our assistance on scene.
Our ability to provide this care at no cost is powered by grants and by the generosity of our community. That funding equips our physicians and keeps them ready to respond.
Can a patient or member of the public request MD3?
No. MD3 cannot be requested directly by patients or the general public. We are a specialized medical resource that works within the existing 9-1-1 system to support public safety personnel on scene.
If you are experiencing a medical emergency, call 9-1-1 immediately. The dispatcher will send the appropriate help, such as an ambulance or fire department. If the responding crew determines that physician-level support is needed, they will request MD3.
How do public safety agencies request MD3?
Any area EMS or fire agency can request an MD3 physician through its dispatch center or by calling 207-861-4244.
This line is for public safety agencies only. Members of the public should always call 9-1-1.
